value of royalchrome chairs

I have two Royalchrome chairs, low to the ground with half circle
arms and black wooden arm rests. The label on one of them is
in mint condition. They are covered in naugahide(sp.?) one red
the other mustard. The chrome is pitted and they are very rusty,
something I've tried to fix myself, to no avail. First question: what
is their value as is? Second question: Are they worth refurbishing
and if so how does one go about re-doing the chrome?
